You mention 5eqs but i use mine with 10 bands (only 2 front channels)I guess the same info still applies.Also,my meter does mention something about 2 different settings for A and C weighting.I know there was no chart though to adjust the levels against.Do you know if i should set it for A or C?The unit is a Radioshack digital readout SPL


Maybe the digital version has onboard correction, although I doubt it. I've just checked my analog SPL meter manual. The chart is actually labelled 'response curve'. This shows what the meter will claim the levels are at for a 0dB actual level across the frequency range.

Use the C weighting. This is a flat response from 20Hz-2kHz, within 4dB from 2kHz-10kHz, and then drops off at higher frequencies.
The A weighting is designed for safety-related SPL readings.
